Actually looking at them both since my last engine was a grubee the head milling is quite different to be honest the stinger looks totally different and the carb is different as well. I just got the SD kit today and i installed it in about 2.5hrs.
The SD fired right up and feels like it even has more power. Awesome engine!! Not sure where you get your info??
